Main Group Metal Halide Complexes with Sterically Hindered Thioureas. XVI. The Synthesis, Characterization, and Crystal Structures of Two New Complexes Of 1,3-dimethyl-2(3H)-imidazolethione with Indium Trihalides
Chemistry and Biochemistry
In an attempt to prep. complexes analogous to the bis-dmit adducts of Group 15 trihalides [dmit = 1,3-dimethyl-2(3H)-imidazolethione], In(dmit)2X3 (X = Cl, Br) were synthesized and characterized. The crystal and mol. structures for both of these compds. showed a distorted trigonal bipyramidal configuration with the thiones and one halide occupying equatorial positions and the two remaining halides arranged in a near-linear X-In-X axial grouping (X = Cl, Br). This stands in contrast to the dimeric distorted octahedral structures obsd. for BiCl3(dmit)2 and SbCl3(dmit)2. The far-IR and laser-Raman spectra as well as soln. state proton and solid state 13C NMR spectra are reported.
